Most of the difficulty of including AI in the standard collection of sciences is that there are recurring features of the best or most-publicized work in AI that are hard to fit into the conventional observation-hypothesis-deduction-observation pattern of those sciences. Some parts of the difficulty can be clarified and resolved by showing that certain details of what is involved in AI have underlying similarities with corresponding steps in other sciences, despite their superficial differences. The treatment of ‘theories’ and ‘programs’ below is intended as a commentary on that remark. A further part of the difficulty is that AI still lacks some scientific credibility because it does not yet seem to have the standard of reproducibility and communicability of results that is built into other sciences. The difficulty is illuminated by activities in AI research that have come to be known as ‘rational reconstructions’. While the earliest attempts at rational reconstruction have generally been less than successful, the idea itself is potentially useful as a means of generating new knowledge or mapping out new territory in AI.
On theories, models and representations
Sciences are supposed to have underlying theories, and technologies rely on theories through the help of their supporting sciences. The first hesitation among outside observers to give AI full credit for being a science or technology comes from the difficulty of identifying AI's theory or theories.
